dc.description.abstractANSTO successfully operates one SANS instrument Quokka and in January of year 2016 commenced user operation of the second SANS instrument, Bilby [1]. The Bilby is the utilizing both Time-of-Flight and monochromatic capabilities. The design (in particular, set-up of four choppers which uses idea of that for D33 instrument [2] at ILL) opens possibility to vary wavelength resolution in the wide range (from 4% to 30%). Two arrays of position sensitive detectors in combination with utilizing of wide wavelength range (from ~3Å to ~18Å) provide capability to collect scattering data of wide angular range without changing experimental set-up (the most common settings used by now allow simultaneous data collection in the range between 1·10-3 Å-1  0.6Å-1). Offered instrument design opens possibility to collect scattering from a wide range of samples, with a unique capability to record fast kinetics data. The presentation will be focused on general concept and unique features of the new SANS instrument, as well as some results of instrument commissioning and operation. Data reduction algorithms implemented in Mantid software [3] will be presented. Also, some principal difficulties in use of ToF mode comparing to monochromatic set-up for soft matter samples will be discussed.en_AU
